Career

Grollmus was born on 8 January 1918 in Lissa, at the time in the Province of Posen, a province of the Kingdom of Prussia. Today Lissa is Leszno in western Poland. Following flight training, Grollmus was posted to the Ergänzungsjagdgruppe of Jagdgeschwader 54 (JG 54—54th Fighter Wing), a supplementary training group, in November 1941.{{sfn|Obermaier|1989|p=122}} On 9 March 1942, the Ergänzungsgruppe of JG 54 was disbanded and the pilots were transferred to I. Gruppe (1st group) of JG 54.{{sfn|Prien|Stemmer|Rodeike|Bock|2005|p=260}} In consequence, Grollmus was transferred to 2. Staffel of JG 54. As part of a Luftwaffe plan to exchange fighter units operating on the Eastern Front with fighter units flying on the Western Front, Grollmus was assigned to 12. Staffel of JG 54 in July 1943 which had been newly formed from elements of 7. Staffel of Jagdgeschwader 26 "Schlageter" (JG 26—26th Fighter Wing) and 4. Staffel of JG 54 and was subordinated to II. Gruppe of JG 54.{{sfn|Prien|Stemmer|Rodeike|Bock|2012|pp=223–224, 264}}

Summary of career

=Aerial victory claims=

According to US historian David T. Zabecki, Grollmus was credited with 75 aerial victories.{{sfn|Zabecki|2014|p=1615}} Spick also lists him with 75 aerial victories claimed in an unknown number missions on the Eastern Front.{{sfn|Spick|1996|p=237}} Heaton, Lewis, Olds and Schulze also list him with 75 aerial victories.{{sfn|Heaton|Lewis|Olds|Schulze|2011|p=236}} Mathews and Foreman, authors of Luftwaffe Aces — Biographies and Victory Claims, researched the German Federal Archives and found records for 68 aerial victory claims, all of which claimed on the Eastern Front.{{sfn|Mathews|Foreman|2015|pp=429–431}}

Victory claims were logged to a map-reference (PQ = Planquadrat), for example "PQ 10163". The Luftwaffe grid map ({{lang|de|Jägermeldenetz}}) covered all of Europe, western Russia and North Africa and was composed of rectangles measuring 15 minutes of latitude by 30 minutes of longitude, an area of about {{Convert|360|sqmi|sqkm}}. These sectors were then subdivided into 36 smaller units to give a location area {{Convert|3|x|4|km|mi|abbr=on|sp=us}} in size.{{sfn|Planquadrat}}
